Abstract
The utility model relates to a concentric bridge integrated water distributor, which solves the problem that a packer or a water distributor can not be suitable for multilevel stratified water filling. The utility model is characterized in that an assembly (4) with two via holes (8) and a piston sleeve (3) are respectively fixed outside and in an upper and a lower joints (1 and 12); a working cylinder (15) is arranged in the assembly (4) corresponding to the via holes (8); the inner wall of the working cylinder (15) of both sides of the via hole (8) are provided with grooves; then, the interior of a working cylinder (15) is sheathed by a packer (14) of a water nozzle (7) communicated with the via hole (8); the end heads of the packer (14) and the working cylinder (15) are sheathed with filter sleeves (2) with a ciconial ring (13); the rubber cylinder (9) is mutually clamped with a spacing ring (10) is arranged in the middle of the piston sleeve (3). The utility model has the advantage of simple manufacturing process and is suitable for multilevel stratified water filling; the flushing successful rate is high, the test is convenient, the service life of the water distributor can be extended.
Description
Technical field:
The utility model relates to a kind of special tool of separated-zone water infection oil field, belongs to the integrated injection well downhole flow regulator of concentric bridge-type.
Background technology:
At present, when water injection well in oil fields seperated layer water injection, quantitative injection operation, all use injection well downhole flow regulator, and in order to satisfy the seperated layer water injection needs,, be provided with packer at interlayer mostly and utilize cementing truck to build the pressure to set the expense height because shorting appears in a variety of causes, operation, closing well etc.Existing packer is separate type with concentric injection well downhole flow regulator, mostly is Pyatyi most.The problem of Cun Zaiing is more like this, and cost is big, and labour intensity is big, but subject matter is: the lob test is adopted in test, step-by-step measurement from bottom to top adopts diminishing method to try to achieve the layering injection rate, plays pendulum and asks for data, inaccurate, allotment efficient is low, and effect is low, inapplicable multilevel hierarchy water filling, test is inconvenient, produces to the oil field to impact.
The utility model content:
In order to overcome the deficiency that existing oil field packer or concentric injection well downhole flow regulator can not be suitable for the multilevel hierarchy water filling, the utility model provides a kind of concentric bridge-type integrated injection well downhole flow regulator, and this injection well downhole flow regulator convenient test can be suitable for the multilevel hierarchy water filling.
The technical scheme that the utility model is taked is: the integrated injection well downhole flow regulator of this concentric bridge-type, form by last lower contact, piston bush and packing element, be fixed with the assembly and the piston bush of 2 through holes inside and outside the last lower contact respectively, the seating nipple that corresponding through hole is arranged in the assembly, the seating nipple inwall of through hole both sides is fluted, had in the seating nipple then with the be connected blanking plug of water nozzle of through hole and entangled mutually, in the termination of blanking plug and seating nipple with the filter ruffle phase site of band conical ring; In the middle of piston bush, be equipped with the packing element of spacer ring phase clamping.
The utlity model has beneficial effect: because this integrated injection well downhole flow regulator has seating nipple and piston bush respectively inside and outside assembly, thereby formed central passage, can adapt to the multilevel hierarchy water filling, can control two-layer section water injection rate for every grade, there is last lower channel to become split channel again, in the time of can avoiding testing, delivers, salvage the resistance of blanking plug, technology is simple, size significantly reduces, and sealing effectiveness but improves greatly, well-flushing success rate height, make things convenient for test, prolonged the application life of injection well downhole flow regulator.
Description of drawings:
Fig. 1 is a sectional view of the present utility model.
1-top connection, 2-filter ruffle, 3-piston bush, 4-assembly, 5-well-flushing valve, 6-well-flushing valve seat, 7-water nozzle, 8-through hole, 9-packing element, 10-spacer ring, 11-pin, 12-lower contact, 13-conical ring, 14-blanking plug, 15-seating nipple.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, the integrated injection well downhole flow regulator of this concentric bridge-type is by last lower contact (1,12), piston bush 3 and packing element 9 are formed, last lower contact (1,12) external and internal fixation has assembly 4 and piston bush 3, assembly 4 has 2 through holes 8, assembly 4 is equivalent to the main body of existing packer or the seating nipple of injection well downhole flow regulator, packer and injection well downhole flow regulator are organically combined, and assembly 4 is built-in with the seating nipple 15 of corresponding through hole 8, and at seating nipple 15 inwalls of through hole 8 both sides 3 grooves is arranged, and forms the central passage level Four, be referred to as concentric bridge-type in the oil field, can control two-layer section water injection rate, existing radial passage, i.e. injection channel for every grade, simultaneously there is last lower channel to become split channel again, delivers in the time of can avoiding testing, salvage the resistance of blanking plug; Had in the seating nipple 15 then with the be connected blanking plug 14 of water nozzle 7 of through hole 8 and entangled mutually, in the termination of blanking plug 14 and seating nipple 15 with filter ruffle 2 phase sites of band conical ring 13; Be equipped with the packing element 9 of spacer ring 10 phase clampings in the middle of piston bush 3, spacer ring 10 touches well-flushing valve 5 mutually by well-flushing valve seat 6 more afterwards.
When the needs anti-flushing well, oil pipe emptying, the sleeve pipe pressurization, well-flushing valve 5 moves up at this moment, leaves valve seat 6, and the well-flushing passage between piston bush 2 and the assembly 3 is opened, and can finish clean-out service successively, the success rate height.
When the needs water filling, casing pressure is lower than the oil pipe internal pressure, and well-flushing valve 5 moves down, and closes the well-flushing passage.
When needs set, owing in the piston bush 3 on packing element 9 tops and the cavity between the assembly 4, an atmospheric air chamber is arranged, under the effect of underground pipe casing internal pressure, produce one and be enough to make the thrust of moving on the piston bush 3, thrust is cut off pin 11 and is compressed packing element 9, it is set, avoid using cementing truck to build the pressure and set, cost reduces greatly.
